Going to live alone for the first time

Never been alone my entire life.I took a flat recently for myself close to my workplace.I plan to make it really cozy and perfect , basically do everything I always wanted like a good desk setup ,home decor,cozy lights. On one hand it feels adventurous and fun to be alone and peaceful,focus on work ,hit gym and basically improve everyday but I also feel like I might feel lonely after a while and maybe feel depressed?. How do I deal with this feeling.
